You are asking two questions that you think are connected but are actually not.
Question 1 - What is the use of eye banks?
Answer: It's to store corneas for transplant for people with cornea damage.
Question 2 - What use is cornea transplant to a completely blind person?
Answer: It depends. If the blindness is due to clouded cornea (several ...

I used to work at an eye bank so I have a bit of knowledge about this, though some of it may be out of date.
There are several aspects to an eye bank. The corneas are one of the primary things that are kept for transplantation. Of course, this will not repair blindness in someone that has problems in other areas of the eye, but corneal transplants are ...

Fetal RNA - mRNA and microRNA - has been detected in maternal blood as shown in this report. Here's a second report showing how fetus gives back to repair the maternal myocardium - fetal cells traffic to an injured maternal myocardium and undergo cardiac differentiation.

No-one can re-implant an entire eye, because the optic nerve has been severed in one who has lost an eye. A cornea can't be grafted to a glass eye. But blindness isn't only caused by loss of the entire orbit. It's also caused by cloudy corneas, which is the purpose of eye-banks.
The optic nerve is a cable of nerve fibers that carry visual information from ...

The epidermis is a four- or five-layered epithelium. The top layers are squamous whereas the bottom ones are more columnar (http://en.wikipedia.org/wiki/Epidermis_(skin)). The lowest layer is separated from the dermis by the basal membrane (a.k.a. basal lamina, basement membrane).
The process of wound healing in skin is extremely complex and obviously ...

It would first be good to look at the different layers within the skin as you mentioned in your question.
The skin is made up of:
Epidermis: the outermost layer of skin, provides a waterproof barrier and creates our skin tone
Dermis: beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands
Hypodermis: ...

It seems to me that really your whole question seems to be much simpler than it seems and it is just
"why are eye banks called eye banks when they can't transplant eyes, just bits of them like corneas"
The answer is:
In the english language and in various cultures, the names of things often have a loose and not entirely accurate relationship to the ...

In addition to providing tissue for transplant, eye banks also provide tissue from all parts of the eye to medical schools and universities for teaching and research purposes. There are many medically relevant questions that can only be answered by examining human tissue, and eye banks facilitate this research.

The eyeball is basically the sclera that surrounds the delicate inner structures of the eye (see wiki on the eye). The cornea is the transparent window in front of the pupil that transmits light to the retina. It needs replacement when it turns opaque, often due to damage or infections. The cornea can be replaced on its own, without the need for ...

UV rays cause damage is by thinning the walls of surface blood vessels, leading to bruising, bleeding, and the appearance of blood vessels through the skin. Longwave UV radiation (UV-A) accounts for up to 95% of the UV radiation that reaches the earth's surface. Although UV-A is less intense than UV-B, it is more prevalent and can penetrate deeper into the ...

Saying protein in general helps to heal wounds is a very far step. Different proteins are essential for nearly every process that happens anywhere in your body.
There is a range of proteins which is required specifically for wound healing. The first step of wound healing is blood clotting in order to close wounds. This uses several so-called clotting ...

I heard that as well and was skeptical at first, but apparently there IS science to support it- http://mblogs.discovermagazine.com/80beats/2011/11/21/helpful-mouse-fetuses-naturally-send-stem-cells-to-mom-to-fix-her-damaged-heart/ Officially found with mice, but it supports how some women that suffered damages while pregnant are sometimes found with their ...
